Definitions

  • the decoder At reception of the ECM message, the decoder generates a random number R 1 comprised between 0 and 1 and if it is smaller than the probability P, the decoder generates another random number R 2 defining the moment M of connection within the time period T of one minute or the waiting time before connection.
  • the managing center transmits this message all minutes allowing all active decoders to connect. These connections are accounted by the managing center in order to increase the probability P in function of the number N of decoders already updated.
  • the probability P can progress from 1/1000 for example to 1/900, 1/800, 1/700, etc. Taking in account a rate of active decoders of 80%, the initial probability P can be increased to 1/800.
  • connection probability P is adapted for maintaining the value of the processing load rate of the server according to a value defined by the server whatever is the number of active decoders connected to the network.
